frost bomb or tempest in rbgs? starting rbgs tonight for the first time, not sure about that.

Frostbomb, you basically can solo anything with Frostbomb and couple Frostbolts, specially in RBG's where you can mostly freecast all the time. Then again NT is almost as good as full row of wlock dots and gets better if you multidot which feeds you procs. Whatever you like tbh, I like to cast so I choose Frostbomb.

Incanter's Ward is no longer transferred to a Mage who Spellsteals it, but is dispelled from the target.
Living Bomb now deals 70% of its damage when used against other players, down from 100%.
Nether Tempest now deals 70% of its damage when used against other players, down from 100%.
